INDIANAPOLIS — Andrew Luck's big secret is finally out. He's been throwing a football for weeks — and now he's throwing in public, too.

Nearly 17 months after undergoing surgery on his injured right shoulder, Luck jogged onto the practice field Tuesday wearing a red jersey, strapping on a helmet and picking up a special ball as he started throwing in front of reporters for the first time since October.

No, it wasn't a regulation NFL ball and the longest pass he attempted was only about a 20-yard lob, but it still was progress.
